i i SEPARABLE Application fil'ed'i June s;

To all whom it mmy: concern: 1:. Be it known that LCHAnLus M, Ron1nsonaa citizen of the United'States,residing at WTaterbury,-in the county of New Haven and State of Gonnecticut, have lnvented a certain newland usefulimprovement in separable i Fasteners,

i or automobile curtains and'thelike.

5 The object o-fithe invention is rlBO provide a separable fastener of simple andeheap con-r struction, and having few parts, all of which are otrugged and durable construction, and

hencenot apt to become broken or inoperatire during the. ordinary pontinuecl-andrough usage'to which such fasteners are subi but showing the stud-engaging member in jeeted.

The 111- 660131011 consists ina separable fastener having a socket member comprising a:

i back plate and a face plate and a slidableresil ient stugil 'engagi-ng member mounted therebetween, anda stiidyhavlngahead, a shank and a"-'neck underlying sarddiea'd, the studi engaging member adapted to 1 engage the i stud at its neck, asl will proceednow to ex-- plainand finally claimq r:

of whicl r-the following isa ful1, 'Theasocket :membe'rweomprises essentially a---ba-,ek-p1ate 1, having a. setting eyelet 2,

preferably integral therewith and providing an aperture in-the"baok plate,-and an up- 7 "turned flange 3.

, Upon the-back plate is mounted a fille-ribloek bout-put as at 5 to form working space" for. the 1 resilient arms: (ixo'f the -stud-engag1ngmember, and having grooves? -lI1 which-these arms are i adapted to. slide, and a guide 8 to keep the stud-engaging member properly alined for.

assembled upon the back plate and within its is -el osed over; ant-l *clinched upon the back filler block and studeengaging member are i of the baoloplate, as at.12,-butobviously othersuitablewways of imiting these parts may be; employed. The stud-engagingmember i is prov-idedwith an operatingextension 13- projeetinge eXter iorly' of the socket member. It will be notedthatthe filler block 4; "is of lgreaterwthiekness than the thickness o f-the stud-engaging member, thereby providing a :slight clearance between: the sti'id-engaging ingthe invention, in the seve 'alfigures of -ymembenand the back and faoeiplates; where- 35 by {jamming of the studengaging member Figure 1 is: a face" view showing tlie fas between the back andface plates duringthe iliseugaged position, as inFig. 2. Fig. 6 is a seetional'viewsimilar toFlg. lpbut show-'- ing the parts in tlie-piiisit ons assumed when the: socket member is beingforcedupon the 1 -stud-head*. Fig. '7 is a seetiongtaken inthe operation of assembling, and thereafter dur ingoperation, is'wprevented-yand free sliding,movement thereofensured. The resilient arms '6 of -the studeengaging nie nber are deflected as at 14k toformstops adaptedqto abut against theyupper iace 15 otthe cut-out portion of thefillerbloek to limit tl eoutward 'u'ioven'ient ot the stud-en paging;- member witlrrespectthereto and prevent 1tS- withdrawal -i'ro'r'n the socket ,meznber, and thesestops also serve to limit the inward motion of the stud-engaging 'member by their-eont'aetwrth the lower face 16 of the cut-out portion or the hller block.

The stud of the fastener comprises a head 17, H shank 18 and a neck IQ-ofreduced di- ,1'5 shown in Fig.3. i

fastened, but other means of attaching the v stud may be used to suit other conditions.

The socket member of the fastener may be attached to a carriage curtain or the like 23 by means of a washer 24 upon which the end of the eyelet 2, which passes through the material of the curtain, may be clinched, as

Theoperation of the fastener. is as follows Whenit is desired to attach the socket member to the stud, assuming that the parts ofthe socket member are in the position shown in Fig. .4, it is merely necessary to position thesocket member with its aper tures arranged substantially axially of the stud, and then exert pressure upon the socket member toward the stud, which pressure will cause the head 01 the stud to force apart or deflect the resilient arms 6 of the stud-engaging member substantially radially of the aperture, as shown in Fig. 6, until the head extends past them, whereupon they will, by their resilient action, return to their normal position (as shown in Figs. 1 and beneath the shoulder 20 of the head of the stud and in frictional engagement with the guide 8 and the neck 19 of the stud.

it will thus be seen that disengagement of the socket member from the stud will be impossible so long as the stud-engaging member remains in this position, and the frictioual engagement of the arms 6 of thestud engaging member with the neck 19 and guide 8 will revent accidental displacement of it outward engage the socket member from the stud, the stud-engaging member will be withdrawn to th position shown in Figs. 2' and 5 by means of the operating extension 13, which will completely withdraw the arms 6 of the studengaging member from their position in intersecting relation to the aperture of the socket member and will permit the socket member to be detached from the stud.

It may and sometimes does occur that in separable fasteners "in which a resilient member is used for engaging the stud, contmued use and operation will cause the resilient member to lose its resiliency to some the neck 19 ofthe stud to augment the frie arms maybe so formed ly. Then it is desired to distional engagement of the arms therewith and prevent accidental withdrawal of the stud-engaging member, or only one of the for this purpose as shewn at 26, Fig. 9. a

toner which is very simple, both in construction and mode of operation, and which is not likely to become damaged .or impaired in its usefulness, and, moreover, the stud-engaging member of the fastens is of such a nature that when once it has. engaged the stud when in the position shown in Fig. 4, it is impossible for it to become accidentally sep arated' therefroimand may only be so'separated therefrom when the stud-engaging member is withdrawn as hereinabove described.

.1 am aware thatfasteners have been devised in 1 which a resilient stud-engaging member has been employed,.but in those fasteners of this type with which 1am familiar, either the stud-engaging member is fixed and the socket member is forced on to the stud and released therefrom by resilient deflection of the studengaging'inember, in

'whichcase the head of the stud must be substantially a double cone,'.which has its disadvantages in that the sockehmember may become as easily detached as attached; or'sliding movement of the stud-engaging member is necessary for both the attaching and detaching of the socket memberto and it willthus be seen that I provide a fasopposite direction. because of the shoulder of the stud head; and in that witlnlrawal of the stud-engaging ncmberis necessary only to disengage the socket member fron'i the stud and is not necessaryfor the purpose of engaging it therewith. I

It is to be understood'that although I have herein shown and described a particular embodiment of my. invention, I do not consider it as limited thereto except as de fined by the scope-of the following claims.

apertured face plate, a slidable resilient stud-engaging member, and a filler block assembled between said back and face plates and provided with a cut-out portion adjacent to the aperturesof said back and face plates and providing a working space for said stud-engaging member, said filler block having grooves forming guides for said studengaging member.

S. A socket member for separable fasteners. comprising a back plate, a face plate, a slidable stiu'l-eugaging member having a pair of resilient arms, and a filler block having a cut-outportion providing a working space for said arms and grooves forming guides therefor.

9. A socket member for separable fasteners, com prising an apertured back plate, and

a face plate, a slidable stud-engaging member having resilient arms normally interadapted to engage the neck of said stud by snap action and to be disengaged therefrom by sliding movement.

11. In a separable fastener, a socket memlying said head, said stud-engaging member ber comprising an apertured back plate, an

apertured face plate, and a slidable studengaging member having a pair of resilient arms intersecting the aperturesof said plates and assembled thercbetween, and a stud having a head, a shank, and a neck underlying said head, said resilient arms capable of de-,

fiection substantially radially of said. aper tures when forced against said head and adapted toembrace said neck after the passage of said head therebetween, said studengaging member being slidable so as to withdraw its arms from cooperation with said stud to release said stud from said socket member. V i

12. In a separable fastener, a socket member comprising a back plate, a face plate, and a bodily slidable stud engagingmember mounted therebetween and having a pair of resilient arms, a stud having a head, a shank and a neck underlying said head, said arms adapted to snap over said head and to 'frictionally engage said neck to prevent acciwith said stud-engaging member for positioning and guiding said stud-engaging member, said socket member adapted to en gage a stud by'snap action of said stud-engaging member and to be disengaged therefrom by bodily sliding movement of said s in d -enga gin member.

In testimony whereof I have hereunto set my hand this 16th day of June A. D. 1922.
